a quick connection `of the line ruling mechanism: with the typewriter, to draw a straight', acscurate line and to enable" this line to be raised' orl'owered as desired, to locate it in the line ofk the letters on the machine or to effect underlining of the written matter.

Othervimportant objects of the invention areV to provide the' device in the form of a stylus4 aipproximately theL size of an ordinary writing pen,

so as to' be conveniently handledV and at the same time small enough lto be entered into position and engaged with thl type guide of a: standard writing machine. v

The drawing accompanying and formingpart of the' specic'ation illustrates a present prac'-V tical embodiment ofthe invention. Structure,v however, may be modied and changed as regards the immediate illustration, all. within the true intent andi scope of the invention as hereinafter defined and claimed.

F'lgr 1 in the drawing is a broken cross sectional view illustrating ,a form of the invention as applied to and used on an` ordinary typewritf ing machine, parts of the latter being indicated to thev extent of the platen and type Vguide in front of the platen;

Fig. 2 is a broken perspective view illustrating the ruling attachment as being approached. to the type guide;

Fig. 3` is a front end elevation of the attachment; l

Fig. 4 is a cross sectional view of the attachment on substantially the plane of line 4-4 of Fig.' 5 is av horizontal Sectional view ofv the sup.- porting and guiding 'structure on substantially the plane of line 5 5 of Fig. 3.

In Fig. 1, the platen of a typewriting machine is indicated at 6 with a type guide 1 in the usual position in front of the same.

The guide 'i is usually constructed aboutr as show-n in- Fig. 2. withforwardly' extended ngers 8 spacedto aiTord" avc'onvergen-t throat or guideway' 9 between the-samev for the type'barsf.

The present invention make use of this guide for locating and holding a ruling implement in engagement with the sheet on the platen.

Specifieallythe. drawing or ruling implement is shown as a ball point pen IU seated' in an eccentric bore ll in a cylindrical support l2' ro-` tatably confined in a cylindrical barrel or casing i3.

The latter has a baseA structure to t thev com` pani'on fingers ofthe type guide, and this is shown in Fig. 3'- as ay dependent shoe I4 at the underside of the forward portion of the barrel convergently grooved in the opposite sides at I5 to slidingly engage in the convergent guideway 9? of the type guide.

The tapered fit of the supporting shoe in the type guide' centers and steadies the drawing implement and may be designed to limit the for- Ward projection of the implement to prevent excessive pressure against the platen.

This construction affords a quick and easy way for engaging the implement in the machine and' for holding it accurately in position while the. car-r riage is shift' horizontally for ruling horizontal lines, and rotated for ruling vertical lines.

The` amount of pressure desired for ruling these lines may be governed by the hand holding the pen in position on the type guide, while the other hand is employed for shifting the carriage or rollingv the platen.

The ball point pen is of particular advantage vinv enabling as much pressure asmay be needed for ruling either horizontal or vertical lines and for drawing continuous lines just as freely with the carriage shifted horizontally in either direcf tion or the platen rotated vertically in either direction.

The eccentric disposition of the pen in the mounting support enables lines to be drawn either in line with the letters, as for lining out or for connecting horizontally spaced letters ior numbers,` and for underlining orr overlining printed' subject matter.

To set; the pen in these different positions there is provided, in theillustration, a spring clip I5 riveted or otherwise flxed at 'l to the plug I8 in the end of the eccentric bore Il, so that it may be used as a handle for rotating the cylinder l2 and eccentric pen in the stationary casing I3. The latter is shown as having cavities I9 for engagement by the end of the spring clip to yield- 3 ingly retain the pen in various positions of eccentric adjustment.

The pen with its mounting structure is of relatively small size so that it will readily go into the space left at the front of the platen and be easily engaged with the type guide. When not in use the pen may be laid aside and kept handy as a typewriter accessory. The pen itself may be `a conventional ball point pen of proved construction and the mounting for the same may be produced at low cost, so the entire device may be wholly practical from a cost standpoint.

The sliding engagement and guiding of the pen guide, a cylindrical support rotatably adjustable in said casing.

3. A'lruling device fdratypewriter ofrconventional design having a platen and a type bar guide in front of the platen and comprising a inthe type guide, in addition to denitely locat-V.

ing and holding the pen in proper position for ruling, allows for applying sufficient pressure to eiect ruling of any usualI number of carbon cylindrical casing having a mounting grooved in oppositesidesV to slidingly engage in the type bar guide, a cylindrical support rotatably adjustable in said cylindrical casing, a ball point pen mounted in eccentric relation in said cylindrical support copies. In addition to straight lining either vertically or horizontally, the pen may be used to combine these lines to effect boxing of selected portions of typed subject matter.

.In the form of construction shown in Fig. 1, the pen may be inserted in the front end of the eccentric bore I I. It is possible, however, to make the device so that the pen may be inserted into the holder or base portion from the back. In fact, the base may be made quite short, approximately the length of the sliding shoe portion I4, in which case this short base would have a bearing receiving the cylindrical support i2, and the latter would have an eccentric bore I I into which the pen could be inserted from the back. In such a-construction a spring detent such as shown at I6, could be carried by the cylindrical support and engage detent recesses in the supporting head structure, all of similar effect to the structure ilrst disclosed. f

The type guide illustrated at 'I is Aoi' a familiar, conventional design and thesupporting base is shaped to correspond. It will be appreciated that for other forms of type guides the supporting base will be designed and constructed to complement and properly fit the special form of type guide.

The ball point pens used for ruling in the present invention, usually have a small vent at some place in the barrel of the pen. To avoid sealing off this vent when the pen is mounted in the holder, a vent of more or less equal size may be provided for the cavity in which the pen is located, such as a small passage shown at 2D extending through the plug I8 in the end of the pen receiving bore I I.
